FORECAST IN DETAIL

Can we get this cooler wedge of air–courtesy of breezes off the Atlantic–out of here by afternoon? Sunshine will try its best. It could end up being a decent day, but let’s keep our hopes low. The upside? A decently comfortable temperature regime over the weekend. Not to mention a return of full sunshine by Sunday. We get even warmer into next week, with no considerable rain threat until late Monday and into Tuesday it appears.


Clouds: Latest mid-Atlantic infrared satellite shows movement of clouds over past two hours. Refresh page to update. See more maps on our Weather Wall.

Today (Friday): Clouds could dominate from time to time, but indications are that at least some sunshine should be seen. In a fully overcast scenario, late afternoon temperatures may top out only in the low-to-mid 50s; however, upper 50s and low 60s are possible by late afternoon if we see sunshine dominate by early afternoon. Luckily, wind and rain won’t add to our cloudy woes. Light easterly breezes (if they shift, we might see more sunshine!) shouldn’t chill us much, and rain chances stay below 10%. Confidence: Medium

Tonight: Breezes remain fairly light and variable in direction, but southerly becoming dominant. Lower 50s during the evening slowly dip lower, thanks in part to mostly cloudy skies insulating us a bit. Before dawn, low temperatures should bottom out around 40 degrees around Dulles and outside the Beltway. Perhaps upper 40s around National Airport and downtown. Confidence: Medium-High

Tomorrow (Saturday): This one has a good chance at seeing more sun than clouds, as weak system to our north (and a more significant one to our south) stay far enough away, as it appears now. How do how temperatures in the upper 60s to low 70s sound? Not bad, I agree. We just have to watch for more clouds than currently expected, which could keep us a few degrees cooler. As far as breezes go, we will notice northerly 5-15 mph winds at times, so let’s hope clouds don’t shade us too much. Shower chances in and around the Beltway are around 10-20%, but I think the bulk of (or all of) the moisture sliding south stays there. Confidence: Medium

Tomorrow night: Finally a decent chance of clearing skies, and less breeze. Partly cloudy skies should allow a few stars to shine through, and northerly 5-10 mph breezes shouldn’t gust too much. Low temperatures could dip into the upper 30s in the clearest spots furthest from urban development, and upper 40s may be as cool as downtown gets. Confidence: Medium-High

Sunday: The day looks fairly bright and relatively comfortable for those out and about (early or late!). Temperatures climb under the fairly abundant sunshine to, ultimately, late afternoon high temperatures in the upper 60s to mid-70s. Warmest spots will likely be south of town. Confidence: Medium-High

A LOOK AHEAD

Sunday night: We should stay fairly clear and mainly calm. Low temperatures before sunrise could get a bit chilly in the upper 30s to low 40s. So far it appears we should avoid a frost or freeze — good news for gardeners. If we see moderate cloud cover, downtown could hold in the upper 40s. Confidence: Medium

Morning sunshine is a great start to Monday, but clouds could increase as the day wears on. So far it looks like any showers (10% chance) should hold off until after the White House Easter Egg Roll. Get out and enjoy the day, even if not around the Ellipse, with high temperatures in the low-to-mid 70s likely. Confidence: Medium

Tuesday’s substantial cloud cover may turn into showers, especially during the afternoon (40-50% chance). The sun may still have enough influence, though, to get our high temperatures into the mid-70s to low 80s. Lots of sunshine would equate to temperatures above 80, but no sunshine may hold us into the mid-70s. No major complaints, right? Confidence: Low-Medium
